Procedure
A mixture comprising 0.40 g (2 mmol) of 4-(2-chloroethoxy)-2,3-dimethylpyridine N-oxide, 0.30 g (3 mmol) of succinimide, 0.48 g (3.5 mmol) of potassium carbonate and 30 ml of methyl ethyl ketone was heated under reflux for 2 hours, cooled by allowing to stand and filtered. The filtrate was evaporated to dryness to remove the methyl ethyl ketone. The obtained residue was purified by silica gel column chromatography (solvent: CHCl3 /MeOH=19:1) to obtain 0.12 g of 2,3-dimethyl-4-(2-succinimidoethoxy)pyridine N-oxide as a white crystal.
